SQUARING, SPACING, AND GLUING CLAMP.

Speccation of Letters Patent.

Application led May 22, 1914. Serial No. 840,209.

T0 all whom it may concern:

Be it known that I, ROBERT C. RUSSELL, a citizen of the United States, residing in the city of Richmond, in the county of Wayne and State of Indiana, have invented a new .and useful Construction in Squaring, Spacing, and Gluing Clamps, of which the following is a full, clear, and comprehensive speciiication, the same being such as will enable others to make and use the saine with exactitude.

This invention is intended, more particularly, to be employed in the manufacture of furniture, or the like, and the object thereof, broadly speaking, is to provide a clamp adapted for squaring and spacing the frames which are assembled, and for clamping the glued oints together firmly and accurately, the device being adapted to perform the three results at one operation and at the same time, the device being strong and dura ble in construction, easily operated and controlled, and by which the work performed will be absolutely accurate and uniform.

Other minor objects and advantages of lmy invention will be made apparent in the course of the following specification.

The preferred means for carrying out the objects of my invention in a practical manner is shown in the accompanying two sheets of drawings, in which Figure 1 is a top plan view of my clamp, showing the same open, in position to receive the frame or work to be clamped therein. Fig. 2 is a front edge elevation of the clamp. Fig. 3 is a sectional view of the clamp, as taken on the line 3 3 of Fig. 1. Fig. 4 is a top plan view of the clamp, showing the same closed and engaging a frame which is clamped therein. Fig. 5 is a lefthand end elevation of the clamp. Fig. 6 is a perspective detail view of a portion of the eccentric shaft, and of thelever by which it is operated. Fig. 7 is an isometrical detail view, showing one of the movable clamping heads. Andv Fig. 8 is a rear edge elevation of a portion of the right hand side of the device, showing one of the tie-blocks.

Similar indices denote like parts throughout the several views.

In order that the construction, the operation, and the many advantages of my invention may be more clearly understood and appreciated I will now ytake up a detailed description thereof, in which I will set forth the construction and the operation as fully and as comprehensively as I may.

The frame work of my clamp includes a plurality of forwardly and rearwardly extending sills: 1, 2, 3, 4, 5 and 6, the same being arranged in pairs, but all being spaced apart, substantially as shown.

Disposed over and resting across on the front portions of said sills is the front-rail 7, the same being secured to the sills by the respective bolts: c, l), c, d, e and f. Also eX- tending over the sills and secured thereto is the rail 8, which is attached to the respective sills by the bolts: g, 7L, i, y', c and Z. Also extending over the said sills is the rail 9, which is secured to the respective sills by the bolts m, n, 0, p, g and 7'. The rearmost rail is similar to said rail 8, except that it is composed of four members: A, B, C and D. The next rail, forward or rail 8, is composed of three members: E, F and G. The next rail forward of rail EFG is also composed of three members: II, I and J. The rail next to the rear of rail 9 is composed of three members: K, L and M. And the rail next to the rear of rail 7 is composed of four members: N, O, P and Q.

By the above it will be observed that eight rails are provided, the same being arranged in four pairs, which are spaced apart from each other, substantially as indicated.

The rails A, B, C and D are secured to the sills 1, 2, 3, 4, 5 and 6 by the bolts s, z5, u, fv, w and In like manner the rail EFG is secured by the bolts 10, 11, 12, 13, 14 and 15. The rail I-IIJ is likewise secured by the bolts 16, 17, 18, 19, 20 and 21. The rail KLM is secured by the bolts22, 23, 24, 25, 26 and 27. And the rail NCP@ is secured by the bolts es, 29, 3o, si, se and 33.

As shown in the drawings, the members Y 'and opposite to the space between the sills 5 and 6.

Slidably mounted in the spaces between the sills 1 2, 3 4 and 5 6, are the respective bars 34, 35 and 36, the same being adapted to move forward and backward in their respective spaces. The said bars are retained in position, with their surfaces even with the surfaces of the sills, by means of tie-blocks 37, 38 and 39, in the rear, andby similar tie-blocks. forward thereof, as the tie-block 40 shown in Figs. 3 and 5. All of the said tie-blocks being of the character shown in Fig. 8, the same being secured to their respective sills as shown.

Slidably mounted in the space between the members A, B, C, D and the rail 8, is the bar 41. Slidably mounted in the space between the members E, F, Gr, and the members I-I, I, J, is thebar 42. Slidably mounted in the space between the members K, L, M, and the rail 9, is the bar 43. Slidably mounted in the space between the members N, O, P, and the rail v7, is the bar 44.

Formed through the bars 41, 42, 43, and 44, in each square where they cross the bars 34, 35 and 36, is a diagonal slot: 45, 46, 47, le, 49, 50, 51, 52, 55, 54, 55 and sathrough each of which is disposed a set-screw: 57, 58, 59, 60, 6i, 62, 65, 64, 65, 66, 67 and 68, respectively. The vsaid set-screws are rigidly secured in the bars 34, 35 and 36, but

they are adapted to slide in their respective slots, above mentioned, the heads of said screws being above the bars 41, 42, 43 and `44, but allowing each set of bars to move freely endwise. n

Secured underneath and to the rail 7, and the member N, to theleft of the sill 1, is the block 69, which carries on its under face the hanger 70. Likewise secured underneath and to the rail 7, and the member Q, to the right of the sill 6, is the block 71, which carries on its under face the hanger 72.

Eocentwlc-EXtending between hangers '70 and 72 sthe round shaft 73. Formed on the vends of the shaft 73 are thekjournals or pivots 74 and 75, the former being journaled in the hanger 70, and the latter in the hanger 7 2. The said pivots are both located to one side of the center of the shaft 73, in orderto make the shaft 73 eccentric, for the purpose hereinafter explained. Secured on the outer projection of the pivot 74 is the .lever 76, by which the shaft 73 may be rotated. Secured to the under faces of the bars v34, 35 and 36 are the respective yokes 77, 78 and 79, each having a vertical slot therein through which passes the shaft 73, whose diameter is equal to the shorter or horizontal diameter of the said elongated apertures in the yokes, whereby as the shaft 73 is rotated the said yokes will bemoved vforward and backward, and they in turn will move the bars A34, 35 and 36 ina like manner, and consequently the bars 41, 42, 43 and 44 will be moved laterally in .a direction at right Yangles to the movements of "thebars 34,35 and 36, thereby accomplish- -ing'the object of the eccentric.

Fixed clamp-headsr-Secured Vacross to and located near the left hand'ends of the member A and the rail 8 is the fixedclamphead 80; and in line therewith are the corresponding Xed clamp-heads 81 and 82,

the former being secured to thel members H and K, and the latter to the rails 7 and 9.

Securedon the rail 7, and parallel therewith, are the three Xed clamp-heads 83, 84'

cured on the rail 8, over the sill 5 and the` bar 36, in lateral alinement with the clampheads 86 and 87 is the fixed clamp-head 92. Secured on the member O is the fixed clamprhead 100 whose .face is inalinement with the left-hand faces of the heads 87 89 and 91.

The fixed clamp-heads 80, 81, 82 and 100,'

all face to the right; the heads 83, 84, 85, 86, 88, 90 and 92, all face rearward; while the heads 87, 89 and 91 face both to the rear and to the right.

Mona?) le cZamp-heads.-Adjustably mounted on the bar 34 are the four movable clampheads 93, 94, 95 and 96.` Also likewise mounted on the bar 35 are the three movable clamp-heads 97, 98 and 99. Also Yin like manner mounted on the bar 36 are the two movable clamp-heads 101 and 102. Mounted on the'bar 41 are the movable clampheads 103 and 104, the former nearthe left end and the latter near the centerof the bar 41. Mounted on the bar 42 are the movable clamp-heads 105 and 106, vthe former near the left end and the latter near the center of the bar 42. Mounted on the bar 43 are the clamp-'heads 107 and 108, the` former vbeing directly forward of and in line with the heads 103 and 105, and the latter being directly forward of and'in line with the heads 104 and 106. Mounted on the bar 44 are .the clamp -heads 109 and v110, thei former being directly forward of and in line with the heads 105 and 107, and the latter being directly forward of and in line with the heads 106 and 108. .Extending upward from the rear ends of the sills land 2, vare the fingers 111 and 112respectively.

In Fig. 4 I show the frame which is intended to form the front of. a cabinet or the like, and it comprises the outer stiles R and S, the central stile T, the top rail U, the bottom rail V, and the two cross bars Y'and Z, which divide the vspace between the Stiles R and T. Y

Modus operandi-It is now evident that that if the'lever76 be turned rearward, as

in Fig. 1, that-thebars 34, v55 5.11666 will' be moved rearward, and the bars 41, 42, 43 and 44 will be moved to the right, thereby opening the clamp and placing it in position in which it is shown in Fig. 1. The loosely assembled frame to be clamped, whose members are framed together, and the joints supplied with glue, may now be placed in position in the clamp, with the left-hand edges and the forward edges, of the various members of the frame to be clamped in contact with the several permanent clamp-heads. Now if the lever 7 6 be moved forward, to the position shown in Figs. 4 and 5, it is evident that the movable clamp-head will be pressed against the right-hand edges and the rearward edges of the members of the frame thereby bringing the several members of the frame to accurate positions relative to each other, substantially as shown in F ig. 4, and also pressing the glued joints tightly together, where they may be further secured, in any well known manner as desired.

It is to be understood that while the construction herein shown is arranged for a certain size and style of frame to be clamped therein, yet it is not to be limited thereto, but the several clamp-heads may be differently arranged from that shown, to give a great latitude, in order that various kinds of frameworks may be similarly clamped therein, in substantially the same manner as shown.

Having now fully shown and described my invention, and one means for its arrangement, what I claim and desire to secure by Letters Patent of the United States, 1s-

l. A squaring, spacing, and gluing clamp, comprising a plurality of sills arranged in pairs forming a guide-way between the members of each pair of sills, a plurality of rails across said sills and arranged in pairs forming a guide-way between the two members of each pair of rails, a forwardly and rearwardly movable bar mounted in each guide-way of the sills, a laterally movable bar mounted in each guide-way of the rails, Xed clamp-heads carried by the rails, movable clamp-heads carried by the bars, and an eccentric adapted to move one set of bars forward and backward and to move the other set of bars laterally at one operation, whereby the movable clamp-heads are caused to move toward or away from the fixed clamp-heads, all substantially as shown and described.

2. A clamping device comprising sills arranged in pairs, rails arranged in pairs and crossing` the sills at right-angles, a bar adapted to slide endwise between the members of each pair of sills, a bar adapted to slide endwise between the members of each pair of bars, set-screws carried by one Set of bars and adapted to slide in diagonal slots formed through the other set of bars whereby when one set of bars is moved endwise the other set of bars will be moved endwise at right-angles thereto, clamp-heads carried by the several bars, fixed clampheads carried by the rails and oppositely disposed to movable clamp-heads, an eccentric adapted to move all of the said bars endwise at one operation of the eccentric, all substantially as shown and described.

3. A clamping device comprising sills, bars slidable between the sills, rails disposed at right-angles across the sills, bars slidable between rails, means whereby the movements of the first mentioned bars will cause the second mentioned bars to move at right-angles thereto, an eccentric for operating the first mentioned bars, a lever for operating the eccentric, fixed clamp-heads carried by the bars certain of which face in one direction and the others facing at rightangles thereto, movable clamp-heads carried by all of said bars and adapted to move toward and away from the fixed clamp-heads, all substantially as shown and described.

In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
